Michelle Obama got a romantic treat from her husband, Barack Obama who turned up during her book tour stop in Washington, D.C.

The former US first lady got surprised by her husband, Barack Obama popped up on stage of her book tour with flowers in hand.

“This is like — you know when Jay-Z comes out during the Beyoncé concert?” the former president said, according to CNN. “Like, ‘Crazy in Love’?”

“It’s the same thing. It’s just a little sample to enhance the concert,” quipped the 57-year-old, who attended the On the Run II tour in July with Mrs. Obama, 54, and had Beyoncé perform during both of his inaugurations.

Michelle Obama also provided a more concise explanation for what distinguishes the two presidents from one another: Obama put country first; Trump puts himself first.

As Mrs. Obama explained, “That motto is his motto,” referring to her husband. She continued, “I say that because that’s how Barack operates,” adding, “I mean there’s so many times when I just want him — like I know all of you — to just curse them out.”

So why didn’t her husband go full Trump as president and personally demean and ridicule his opponents on social media and at rallies? As Mrs. Obama explained, the reason why a person would go “low” is simple: “Oftentimes, going low means you’re acting from a place of ego. You’re really just satisfying your immediate need to lash out.”

Then she shared two key lines that summed up her husband’s guiding philosophy on why he avoided going “low” in response to his critics: “The president isn’t the president for his own ego. The president is the president for the entire country.”

“That, my friends, crystalizes one of the primary differences between the 44th and 45th Presidents in a simple yet effective way. While Obama strived to put his ego second and be the president for all Americans first, Trump is the opposite. Trump is all about Trump. He’s the king of personal victimhood and lashes out whenever his ego demands, be it attacking the media as “fake news” or going after late-night comedians for being “unfair” to him.”
